This book consists of two open letters by the young John Calvin to evangelical believers who desired to stay and work within the Roman Catholic Church.

The first letter exposes the idolatry involved in the Mass, while the second denounces the papal abuses of the pastoral office of the church. Together, they form a resounding call for the necessity of a thoroughgoing Reformation.

This translation from David C. Noe makes the two letters available together for the first time in English. Noe also provides a helpful introduction to Calvin’s early life and the problem of evangelical believers remaining in the Roman Catholic Church.

This book does not merely provide a helpful view of how Calvin believed the moderate French reform movement should decide between God and the worship of false prophets. It is also an opportunity for us to reflect on the abiding significance of the need for reformation.
